IMPROVEMENT IN MECHANISMS FOR SETTING EYELET-HOOKS.

Specification forming part of Letters Patent No. 195,341, datedSeptember 18, 1877; application filed February 15, 1877.

To all whom it may concern:

Be it known that I, JOHN CHARLTON, of Newark, in the county of Essex andState of New Jersey, have invented a new and useful Improvement inMachines for Attaching Eyelet-Hooks to Leather, 850., which improvementis fully set forth in the following specification.

The object of my invention is to make an instrument adapted to fasteningeyelet-hooks of various sizes to boots or shoes which fasten by laces.

The invention consists of a hollow block of steel in the form of aparallelopiped, about threeeighths of an inch square by aboutthirteen-sixteenths of an inch long, the ends being concave, having anaperture about onefourth of an inch square, whose sides are parallelwith the outer sides of the block, and extending lengthwise through it,and having at varying distances from the ends, on every side, two roundholes drilled through the sides into the central aperture. The entireblock is fitted into a slot out into one of the peculiar-formed jaws ofan instrument having jaws and handles jointed together like a pair oftongs, and held in its place by a set-screw, there being a suitablepunch in the opposite jaw for compressing the eyelet, the instrumentbeing opened by a spring or not, and compressed by hand like pliers andby means of the set-screw the block can be fastened or unt'astened, asdesired, or its position altered to suit a change in .the; size of theeyelethook, and then fastened in the altered position.

Figure l in the an exed drawings is a view of the eyelet-rivetinginstrument, containing the block B in the jaw a and the punch P in theopposite jaw a. Fig. 2 is an end view, showing the block B and set-screwS in the lower jaw (1; also a section of the upper jaw a and punch Pthrough the line a). Fig. 3 is a perspective view of the steel block B.Fig. 4. is a view of the jaws a and a, (with part of the handles,)showing the block B and the eyelet E in the block B, and the punch P.Fig. 5 shows two views of an eyelet with its neck and hook complete.

When about to use the instrument for any given-sized eyelet-hooks, ahole in the steel block is first selected which suits the particularsize of the eyelet-hooks about to be used. The block is then insertedinto the slot in the jaw a, and the jaws are closed to force the punch Pinto the selected hole, the block B being placed by hand in the properposition therefor, and while held in this position the set-screw S istightened, thus fastening the block B in the position selected. The jawsmust now be opened and an eyelet-hook, E, be inserted, having the hookinside the block, as shown at Fig. 4, and the leather or other materialto which the eyelet-hook is intended to be fastened having had asuitable hole punched through it, the said hole in the leather isbrought over the neck E of the eyelet, so that the neck projects throughthe leather, when, upon closing the jaws of the instrument, the punch Pwill enter the hollow neck of the eyelet, spreading it open and rivetingit upon the leather, thereby fastening the eyelet thereto.

For other sizes the block is altered and set to suit in the same manner.

1 claim as my invention- 1. The hollow steel block B, made with itsvarious apertures, as shown, combined with the set-screw S andcompressing-instrument a and a, as shown and described, and for thepurpose set forth.

2. The hollow steel block B, made as shown, with its various-sizedapertures drilled at various distances from the ends, adapted for usewith the jaws of an eyelet-hooksetting machine, for the purposesdescribed.
